Sedimentary rock can be changed into igneous rock by undergoing melting and then solidification. At a subduction zone (at a convergent plate boundary, where one plate slides beneath another), layers of sedimentary rock will be assimilated into the mantle.edimentary rock to change to Igneous rock by applying heat and pressure, which creates Metamorphic rock. Next, Metamorphic rock turns to Magma because it melts. Lastly yo â¦ u have to let the Magma cool and it becomes an Igneous rock.
1 Sedimentary rocks are formed through the gradual accumulation of sediments: for example, sand on a beach or mud on a river bed. 2  As the sediments are buried they get compacted as more and more material is deposited on top.3  Eventually the sediments will become so dense that they would essentially form a rock.
